Figure 1.
The Neighborhood Joining phylogenetic tree of HPV-31 variants.
The tree was constructed using HPV-31 variants sequences of partial Long Control Region, E6 and E7 identified in Northern China (NC specimens, N = 6) and variants previously reported in whole genome study (N = 19) [14]. Numbers on the nodes indicated the bootstrap values (1000 replicates) of branches. * NC_001527 was the reference sequence of HPV-31 and it was not one of the sequences identified in the current study. † The sequence of NC-27H9 was the same as IN221709.
